Is most closely related to the Glass-Steagall Act?

The Glass-Steagall Act, enacted in 1933, primarily aimed to separate commercial banking from investment banking to reduce risks and conflicts of interest in the financial system. Its most closely related legislation is the Gramm-Leach-Bliley Act of 1999, which effectively repealed key provisions of Glass-Steagall, allowing banks to re-enter investment banking and insurance activities. This repeal contributed to the financial practices that led to the 2008 financial crisis, highlighting the ongoing debate about the regulation of financial institutions.
